A one-two punch of colder air will sweep across the Chicago area this weekend. The first will arrive in the wake of Friday night's light snowfall as blustery west winds usher more seasonable temperatures into the Midwest. Despite this cool down, Saturday's temperatures will still run a bit above normal.
A second, more potent shot of polar air is due to arrive Saturday night, with the core of coldest air passing across the area during the day Sunday. The arrival of this colder air will be accompanied by another band of light snow or snow showers Saturday night into Sunday morning. This snow will be minor, with accumulations of less than an inch expected. Nonetheless, the combination of subfreezing temperatures, blustery northwest winds and flurries on Sunday will make it seem more wintry.
As has been the case this winter, this brush with polar air will be transitory. Temperatures will begin to moderate Sunday night, leading to a significant surge of mild air on Monday.
